- Nathan Harshman is a mathematical and theoretical physicist specializing in the study of symmetry in quantum systems. He has published articles and book chapters across the subject of quantum physics, including high-energy particle physics, quantum information theory, and ultracold atomic physics. The unifying theme of Professor Harshman’s work is solvability and (to quote Nobel laureate Eugene Wigner) the unreasonable effectiveness of mathematics in the natural sciences. Currently he studies symmetry, topology and control in low-dimensional ultracold atomic systems. These physical systems are at the ragged edge where there is just enough symmetry to find exact solutions and precise control. Any less symmetry and the system descends from the order of cosmos into the disorder of chaos. Professor Harshman has also published articles in the fields of physics education research and the philosophy of science and written book reviews for newspapers and journals. His latest subject of inquiry is topology in quantum systems.
